Class
    Foam::cloudVelocityLagrangianPatch

Description
    A cloud velocity Lagrangian patch. This patch defers to the cloud velocity
    boundary condition to determine the state of a particle after hitting a
    (non-constraint) patch. This allows the velocity boundary condition to
    control the rebound, escape, stick, etc..., behaviour. This is selected
    automatically by the base cloud. The user should never have to specify this
    patch explicitly.
